Abstract:

In order to screen out 1-2 astragalus materials suitable for cultivation and planting in Daqing area of Heilongjiang Province, a comprehensive evaluation method was used to compare and analyze the survey data of 15 biological traits of 23 astragalus materials introduced from the whole country. The regreening rate of the top two materials was above 97%. The thousand seed weight was more than 6.22 g, the underground biomass was more than 28.07 g, the main root length was more than 51.06 cm, the polysaccharide content was more than 17.61 g, and the plant height was more than 70.55 cm. Among them, the top two materials in the comprehensive score of 23 astragalus materials were from Chifeng of Inner Mongolia and Niuyingzi of Heilongjiang. The field growth and the yield and quality of astragalus obtained after harvest were consistent with the comprehensive evaluation results, which were more suitable for planting in Daqing area of Heilongjiang Province.
